UNITEDSTATES PATENT OFFICE HORACE EDN/VARI) FARMER, OF DETROIT, MICHIGAN, ASSIGNOR TO KEISEY-HAYES WHEEL CORPORATION, OF DETROIT, MICHIGAN, A CORPORATION OF NEW YORK MACHINE FOR FORMING HOLES IN yAIsIJEICIfES Application filed June 3, 1929. Serial No. 367,933.

The invention relates to machines for forming holes in articles and refers more particularly to machines for forming spoke holes in the hub members of vehicle wheels. One of the objects of the invention is to so construct a machine that it may be used to form spoke holes in a number of dilerent hub members. Another object is toV so construct the machine that it may be used to form different sets of spoke holes in the same hub member. A further object is to so mount the carrier for the hub member that the hub member may be moved into en gagement with the die in position to be operated upon by the punch. `With these as well as'other objects in view, the invention resides inthe novel features of construction' and combinations and arrangements of parts as more fully hereinafter set forth. i In the drawings Y Figure 1 is a side elevation, partly in section, of a machine embodying my invention;

Figure 2 is a plan view thereof;

FigureB is an end view thereof, partly in section;

Figure 4 is a cross section on the line 4-4 of Figure 1. i

The machine has the base 1 and the ram 2 vertically reciprocable toward and away Jfrom the base. This ram has secured thereto the holder 3 in which is mounted the depending punch 4. AThe 'base has the upwardly extending guides 5 for the holder and has mounted thereon the die 6 for cooperating withthe punch 4. The base has ixedly secured thereto the table 7 upon which is mounted the support for the work article, which latter in the present instance is the sheet metal hubmember or shell 8 of a vehicle wire' wheel. The-support Jfor the hub shell comprises the lower base member 9 which is longitudinally slidable upon the table?, the upper base.

member 10 which is slidable transversely upon the lower base member 9 and a pivotal mounting for the hub lshell upon the upper base member 10. rrlhe lower base member 9 is adapted to be moved longitudinally by means of the plunger rod 11 connected thereto and to a plunger within the air cylinder 12, the latter being mounted upon the table 7 For limiting the longitudinal movement of the lower base member inwardly, there is the set screw 13 secured to the inner end of this base member and engageable with the portion ot the base 1 above the table.7. The upperk base member 10 is adjustable transversely of thev lowerl base member 9 by suitable means such as the threaded rod 14. This upper base member has the vparallel upwardly extending arms or uprights 15 at the upper ends of which is nliloililnted the pivotal mounting for the lhub s e The pivotal mounting comprises the pivotal member 16 having the parallel arms inside and adjacent t0 the. arms 15, the second pivotal member 17 inside the arms of the pivotal mounting 16 and the carrier18 upon the second pivotal member. 19 are aligned pins journaled in the arms 15 of the upper base member 10 and extending into and fixedly secured to the pivotal member 17. f The pivotal member 16 is journaled uponV these pins. For securing the Vpivotal member 16 in its adjusted positions suitable means such as the bolts 2O and the nuts 21 are provided, the former extending through transverse holes in the arms 15 and arcuate slots in the v arms of the pivotal member 16 and concentric with the axes of the pins 19. The carrier 18 has the base plate 22 from which extends transversely Vthe pilot pins 23 for engaging the holes 24 in the hub shell. This carrier has lixedly secured to the base plate the in dexing wheels 25 and 26 which are respectively used in approximately positioning and predeterminedly positioning the carrier.

For clamping the hub shell to the carrier, there is the plunger rod 27 which extends axially through the pivotal member 17 and .through the carrier 18 and is secured at its rear end to a plunger within the air cylinder 28, which latter is ixedly mounted upon the pivotal member 17. 29 is a clamping plate engageable with the hub shell and adapted to encircle the plunger rod and 30 is a suitable washer eno'ageable with the clamping plate and embracing the plunger rod and abutting a shoulder at the front end of. the plunger rod, whichin the present instance is formed by the nut 3l threaded upon the plunger rod.

The pivotal member 17 is connected to the pivotal member 16 by means ot the cam or eccentric 32. This cam has the main portion 33 journaled in the block 34 which is mounted in the guide 35 lixedly secured to the pivotal member 16. The block is slidable in a slot in the guide extending radially from the pivot of the pivotal member 16. rThe cam has at the ends of its main portion the cranks 36 which are journaled in the arms 37 xedly secured to the pivotal member 17. The cam has fixedly secured to one of its ends adjacent a crank 36 the arm 36 which is formed with the L-shaped slot 39. 40 is a slide having the pin 4l engaging in the l.shaped slot, the slide being reciprocably mounted in the guide 42 carried upon the pivotal member 17 and extending transversely of its axis. The arrangement is such that upon downward movement of the slide 40 its pin 4l engaging the arm 38 rotates the cam which, through its cranks 36 engaging the arms 37, causes the pivotal member 17 supporting thehub shell carrier to swing downwardly to lower the part of the hub shell to be punched upon the die 6.

For indexing the hub shell carrier the slide 40 has pivotally mounted thereon Athe dog 43, the nose of which is normally held outward by means of the coil spring 44 to engage a not-ch of the indexing wheel 25 and rotates this indexing wheel in a counter clockwise direction7 as shown in Figure 4, a distance of one notch. This dog is mounted at the lower end of the slide in a position such that it will not engage its indexing wheel until the slide has moved upwardly far enough to 1 rotate the cam 32 to raise the hub shellV from l 'ed upon the guide 42 and having at one end the nose 47 for engaging a notch oi the in- `l dexinor wheel 26 to hold this indexine' wheel from rotation in a counter clockwise direction.

This dog has at its other end the shoulder 48 which is engageable by the spring pressed `bolt 49 carried by the slide 40 to swing` the nose 47 out of engagement with the indexing wheel 26. 50 is another dog in the nature of a bolt having a nose engageable with a notch of the indexing wheel 26 to hold the indexing wheel from rotation in either direction. This bolt extends transversely of the guide 42 and has mounted thereon and extending transversely thereof a roll 5l, which latter extends within the cam slot 52 extending longitudinally in the slide 40. The bolt 49 is positioned relative to t-he shoulder 4S ot the dog 46 and the cam slot 52 is so arranged relative to the roll 5l that the noses of both dogs 46 and 50 are withdrawn from the indexing wheel 26 prior to engagement of the nose of the dog 43 with the indexing wheel 25.

For reciprocating'the slide 40, the ram 2 has secured thereto th-e arm 53 which is formed with the horizontally extending slot 54. This arm is adjustably secured to the ram as by means of the bolts 55 threaded into the ram and extending through transverse slots 56 in the toot flange of the arm. 57 is an upright rigidly secured to the upper base member l0 and having the longitudinally' extending slot 58. 59 is a shoe extending through and slidably engaging in the slots 54 and 58, this shoe being connected to the nut 60 upon the threaded rod 6l. As shown, the shoe is connected to the nut by means of the bolt 62 which provides for rotation of the nut relative to the shoe.r The lower end of the threaded rod 6l is pivotally connected to one end oit the bell crank 63, which is pivotally mounted at 64 upon a lateral extension 65 of the pivotal member l7. The other end of this bell crank is provided with the longitudinally extending slot 66 for receiving the pin 67 upon and extend ing transversely of the slide 40.

With the arrangement as above described, the hub shell carrier be adjusted horizontally in transverse directions and also vertically. This hub shell carrier may also be automatically lowered to engage the part of the hub shell to be punched with the die and may be automatically indexed when raised7 these latter operations being dependent upon movement of the ram. By reason of this adjustable construction, the same machine may be used for forming different sets of holes in the hub shell. Also by substituting different forms of hub shell carriers diii'erent hub shells may be operated upon by the same machine.
